“…For stimulation of growth and increased yield of the crop by AM fungal infection, it is important to lower the amount of available phosphorus and increase the infection ratio (Hayman, 1970;Giovannetti, 1985;Karasawa et al, 2001). In the present study, a high positive correlation was observed between the infection ratio and the density of AM fungi spores in the soil, while a negative correlation was observed between the infection ratio and the amount of available phosphorus in the soybean fi eld (Table 5).…”

“…The density of the fungi in soil must be increased to increase the level of crop infection with arbuscular mycorrhizal (AM) fungi (Hayman, 1970;Giovannetti, 1985). Although the density of AM fungal spores and propagules has been reported for particular regions and upland fields (Tawaraya et al, 1995;Isoi, 1997;Tsuchida and Nonaka, 2002;Saito et al, 2004), data is lacking on the density of AM fungal spores in various regions and soil types.…”

“…Hence if the non· sporing fine endophytes are relatively more abundant in upland tussock soils than in forest or scrub areas, this would also contribute to a smaller spore population in pastures after tussock. Also, because of seasonal effects on spore populations which tend to increase in the summer (Hayman 1970), a possible summer increase in first-year pastures might not have been detected, as the samples were collected in the spring. Phosphate can inhibit mycorrhizal infection and, although spore numbers and the amount of VA infection showed no correlation with the levels of plant-available P in soil, it is possible that some of the higher P values in the sown pastures were the result of recent topdressing.…”

“…After thorough mixing, a small weighed sample (usually 25 g) was wet-sieved to collect root pieces and Endogonaceae resting spores from 700, 250, 100, and 50 I.UTI sieves as described previously (Hayman 1970). Spores were examined and counted in nematode counting dishes (Doncaster 1962) and identified by their morphological similarity to known species (Table 2).…”

Vesicular-arbuscular mycorrhizal fungi (Endogonaceae) were present as resting spores (6-1590/100 g soil) and as root infection (4')0-85% of corte" infected) at 34 of the 35 sites examined. They were most abundant under native scrub and mixed forest and least abundant under tussock grasslands. Their variable occurrence under sown pastures was attributed partly to their abundance under the preceding vegetation; it was not related to soil phosphate availability. Of the 10 species distinguished, the 4 most widespread were the "white reticulate" type, Acaulospora laevis, Sclerocystis rubiformis, and the Glomus fasciculatus group. The absence of distinctive distribution patterns suggests a large measure of ecological equivalence between species.

Effect veness of Mycorrh zal Fung n Agr cultureAbstract: Mycorrhizal fungus forms a mutual benefit as a result of interactions between many plant roots and mycelium structures. While mycorrhizal fungus in this relationship provides essential carbon and organic matter from plants, it also helps to plant uptaking water, nutrients, salt and metabolites. Thus, the both sides in this interaction provide benefit from each other. The important mycorrhizal groups used in various areas of agriculture are endomycorrhizae and ectomycorrhizae. Mycorrhizal fungi and their symbiotic relationships with plant roots is one of the most important example of demonstrating the nutrient exchange between host and heterotrophic organisms feeding patterns that contributes significally to our understanding of the ecological balance in the nature. Nowadays, a large number of effective detection of mycorrhizal fungi that form a symbiotic partnership with the plant has been identified by many studies. This reviewed will be focused on the importance of mycorrhizal fungi use in many areas of agriculture, especially the effects on plant development, plant diseases, the soil fertility and improvement.
